In current task abort routine, if task abort happens to the device W-LU,
the code directly jumps to ufshcd_eh_host_reset_handler() to perform a
full reset and restore then returns FAIL or SUCCESS. Commands sent to the

End users frequently want to know what features their processor
supports, independent of what the kernel supports.
/proc/cpuinfo is great. It is omnipresent and since it is provided by
the kernel it is always as up to date as the kernel. But, it could be
ambiguous about processor features which

Hi Mikulas,
I'll say up front that I think you're barking up the wrong tree
trying to knock down XFS and ext4 to justify NVFS. NVFS will stand
or fall on it's own merits, not on how you think it's better than
other filesystems...
I have some fundamental concerns about the NVFS integrity model,

This patchset updates CascadelakeX events to v1.08 and
updates SkylakeX events to v1.21.
The events have been tested on CascadelakeX and SkylakeX
servers with latest perf/core branch.
The first version was posted a few months ago and now just
resend the patchset with minor update.

Currently, perf-stat with armv8_pmu events with a workload is broken.
This patch set just fixes that.
Before the patch set:
[root@localhost hulk]# tools/perf/perf stat -e
armv8_pmuv3_0/ll_cache_rd/,armv8_pmuv3_0/ll_cache_miss_rd/ ls > /dev/null
Segmentation fault
After the patch set:
When executing perf stat with armv8_pmu events with a workload, it will
report a segfault as result.
(gdb) bt
#0 0x00603fc8 in perf_evsel__close_fd_cpu (evsel=,
cpu=) at evsel.c:122
#1 perf_evsel__close_cpu (evsel=evsel@entry=0x716e950, cpu=7) at evsel.c:156
#2 0x004d4718
After the segfault is fixed, perf-stat with armv8_pmu events with a
workload is still broken:
[root@localhost hulk]# tools/perf/perf stat -e
armv8_pmuv3_0/ll_cache_rd/,armv8_pmuv3_0/ll_cache_miss_rd/ ls > /dev/null
Performance counter stats for 'ls':

I'm adding to the series the new Labrador v3, since it uses the same vendor
prefix. Thanks Andreas, Mani and Rob for your time reviewing it.
Changes since v6:
- Add new caninos,labrador-v3 CoM and caninos,labrador-base-m2 base board
- Improve Model description

Rename nlines to num_lines to be consistent with other usage for fields
describing the number of entries in an array.

Extend gpio-event-mon to support monitoring multiple lines.
This would require multiple lineevent requests to implement using uAPI v1,
